If someone asked you what technologies we'd have 50+ years from now, it probably wouldn't be too different from what others thought would be available today in 2015. First up is the "Flying Carpet Car", which uses compressed air to hover above ground, a precursor to the Maglev trains of today. The description says: "Look, pa, no wheels! Use of a thin layer of compressed air may allow autos to hover and move just above ground level. A pipe dream? Not at all. The concept (already proved) comes from scientist Andrew Kucher, vice-president of engineering at one of our major motor companies. His people are studying how to maintain stability. Special highway engineering is one way. Another is skillful design, evidenced already in experimental ideas from the staff of motor stylist George W. Walker. Today's earthbound cars won't turn into low flying carpets right away. But it may happen sooner than we think!" Continue reading for more.

Upwards lightning is very rare natural phenomenon, with researchers estimating that less than 1% of lightning travels in an 'upwards' direction. This particular event was captured in Tropical Depression Dorian in Florida during August 2013.
And, interestingly, of the three types of this phenomenon known to exist, all three were spotted in this one thunder cloud. According to Dr Ningyu Liu, upward electrical discharges transfer a large amount of electric charge into the upper atmosphere. Continue reading for the video and more information.

Iain Sinclair's Cardsharp2 is no ordinary knife, as it folds up flat like a credit card when not in use. Unlike similar products, this model is thinner and lighter, due to its use of 420 series surgical stainless steel. Don't let its slim design fool you, this knife is sharp enough to easily cut through an automobile safety belt in an emergency. You can pick one up for just $2.80 shipped here.
